Stainless steel round bar is a cylindrical stainless steel product, which is widely used in auto parts, aviation, aerospace hardware tools, chemical industry and other industries. Stainless steel WNR 1.4301 wire is known for its amazing tensile strength and fabric power and is available in a variety of sizes according to customer requirements. They are the product of the best materials and primary strategies that conform to the established norms of the industry. In our assortment we have round rods with special type of ends to ensure short and tight fittings in pipes.

2205 stainless steel sheet has high tensile stress and low thermal expansion and can be used in cargo holds, trucks and ships as sheet.

Alloy 2205 duplex stainless steel sheet is particularly suitable for applications covering the -50¡ãF/+600¡ãF temperature range.

2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength.

Duplex 2205 nuts and nuts are widely used in applications requiring good corrosion resistance and strength in marine and harsh environmenuts.

The notch ductility of SA 240 S32760 Sheet performs well at sub-zero temperatures, down to the -50¡ãC range, while performing well at ambient temperature.

S32760 Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts.

ASTM A240 UNS S32750 plate is suitable for high tension and high corrosion environments.

Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance.

Cold drawn and cold rolled is the primarily prepare for 2205 Duplex Stainless Steel Pipe. Due to the material characteristic of high quality and hardness, duplex steel is more difficult to process than austenitic steel. It is very easy to damage, particularly for small thickness and large diameter pipes, it incorporates a long and hard-working methods.

Super Duplex UNS S32760 Reducing Flanges have a strengthened microstructure, a result of added Nitrogen, allowing fabrication of thin and low-weight flanges that are easy on the pocket.

In general, duplex steel S31803 plate can be used as a replacement for the rather expensive stainless steel alloy grade 904L, as 2205 SS plate has similar properties but is less expensive in composition.

The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.

ASTM A479 Super Duplex UNS S32750 F53 Heavy Hex Nuts are kept together by a combination of their threads’ friction (by means of slight elastic distortion), a small widening of the bolt, and solidity of the components to be held together.

Duplex Steel S32205 bar stock is a ferritic, duplex, austenitic 3% molybdenum, 22% chromium and 5% – 6% nickel alloy stainless steel.

DIN 933 technically ranges from M1. 6 to M52, whereas ISO 4017 ranges from M1. 6 to M64. Secondly, that’s it really, the DIN 933 and ISO 4017 standards are the exact same with the exception of M10, M12, M14 and M22.

UNS S32750 or DIN W.Nr. 1.4410, Duplex 2507 is a super duplex stainless steel conutaining 25% chromium, 4% molybdenum and 7% nickel, designed for demanding applications requiring exceptional strength and corrosion resistance, such as chemical Process, petrochemical and seawater equipmenut.

Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim being to produce a 50/50 mix, although, in commercial alloys, the mix may be 40/60 respectively.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Super Duplex Alloy UNS S32750 (F53 / 1.4410 / Alloy 32750 / Alloy 2507) combines the most desirable characteristics of both ferritic and austenitic steels.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy.
